AUTOMATIC STOVE-DAM PER.

SPECIFIGATIQN forming part of Letters Patent No. 283,106, dated August 14, I883,

. Application filed J anuery 24, 1883. (No model.) 7

To all whom may concern Be it known that I, JOHN C. HIGDON, of Kansas City, Jackson county, Missouri, have invented a new and Improved Automatic Stove- Damper, of which the followingis a full, clear, and exact description.

The object of my invention is to improve that class of dampers which are automatically graduated in the opening which they leave for the escapeof the products of combustion by 4 the draft itself.

- which similar letters of referenceindicate cor- Reference is to be had to the accompanyingdrawings, forming part of this specification, in

balancing the damper, so that when the as-.

' cending' currents become strong by rapid combustion said damper willbe lifted by them and closed against the base f of the outlet 9. The weight is adjustable along'the lever to be shifted, when required.

'To prevent the damper from falling too low I construct the chamber-case with a stud, h, on

which the damper may rest when ithas fallen sufficiently low. To allow the smoke to escape when the damper is closed, I make a hole, z, through it, and provide another damper, j, for

it, that may be set from time to time to reguable opening, n, through the side for the 1e ver 0.

I am aware that a counterpoised damper-is not new; also, that a damper has been made in two sections correspondingly apertured'and sliding one upon the other, so that their apertures will register more or less; but

1. An automatic stove-damper supported;

. for a maximum draft, upon a vertical projection, h, rising from the chamber is, as shown and described. I

r 2. The combination, with the smoke-flue of a stove or furnace, of a damper, b, arrangedto be raised and closed by the escaping products of combustion, and having a smoke-passage, i,

and a damper, j substantially as described.
